In addition to passing two loops of thread successively throu h the work, a feeding movement is impaited to the needle between the' advanci ,g movements to cause the path of the adva cmg movement of the needle in each qase V`d be shifted.

VIn the present construction a linear feeding movement is imparted to the needle to cause the advancing movement of the needle to pierce the Work at a plurality of points loca d in spaced relation to one another. To th end` the needle segment is supported up n a head 26 which is slidingly mounted up n parallel guide bars 27 and 28 rigidly secured in the machine frame.

To this end, the rear end of the carrier is provided with an L shaped member 65 which is engaged by a roll 66 journaled upon the lower end of a back gage lever G7 pivoted between its ends upon the shaft 69. The back gage'lever is rocked automatically at the proper intervals by a face cam formed upon one side of the cam 21 and engaged by a cam roll 72 journaled upon the upper end of the back gage lever.

After both loops of thread have been passed through the work and the first loop of thread has been passed through the second, a pull is exerted upon the supply end of the thread to draw both loops into the work and lock the Stitch. The thread before passing throu h the eye of the needle is carried over a rol journaled in the free end of a take-u lever 86. The take-up lever is fulciume at its opposite end upon the shaft 69 and is actuated from a cam path 88, shown in dotted lines in Fig. 2, and engaged b v a roll 89 joi'rnaled upon the lever between its ends.

During the operation of the take-up lever the end of the supply thread is locked to prevent more thread being drawn from the supply by a thread clamp 92 which binds the thread to the grooved periphery of a roll supported upon an arm 91. The thread clamp 92 is formed upon one arm of a bell crank lever pivotally supported upon the machine frame at 93 und having a roll 9-L journaled upon its opposite arm and engaging with a cam path 95 formed upon the periphery of the cam Q9. The roll is retained in engagement with the periphery of the cam Q9 by a tension spring 96 connected to one arm of the bell crank. In order to vary the clamping effect of the thread clamp 92 it is provided with an adjusting screw 98 which bears against a stud 99 upon which the roll 90 is journaled and limits the movement of the thread clamp in the direction of the roll 90.

In order to completely fill the holes in the work and lock the fastening tightly, a waxed thread is conveniently employed, and to this end. the thread is led from any convenient type of wax pot (not shown) over a guide roll 100, journaled in a liracket 101 secured to the rear portion of the machine frame and from the guide roll to the thread clamp 92.

It is desirable to put some tension upon the thread when passing about the toe in f order that the upper shall be held tightly by the thread, and for this `purpose the thread clamp is conveniently utilized as a.- tension device. The periphersl ;fcani95'is ableioroe tendi provided' with two recessed portions 103 and 104 which allow the thread clamp under the action of the spring 96 to lock the thread during the action of the take-up, and to put' a suitable tension upon the thread when passing about the toe. In the illustratedembdiment of the invention the locking movement of the thread clamp is determined in each case by the position of the ad'usting screw 98, and this movement is su cient to act as a thread clamp to set the stitch in the work when the take-up acts and put a suitable tension on the thread when passing about the toe.

It will be obvious to those skilled in the 1- art that the pressure of the thread clamp may be sufficient to lock the thread when setting the stitch and yet allow the thread to be drawn under tension from the supply when passing about the toe.

In order to increase the efficiency of the thread fastening operation it is desirable to use as little thread as possible and to'secure the shoe in such a manner that the thread fastenings will not interfere in the slightest degree with the inseam sewing operation. To this end, after the thread fastening has been completed and the lock set in the work the supply thread is automatically cut close to the work and the shoe is then fed manually to form the next fastening. In this manner only sufficient thread is employed to make each fastening and the individual fastenngs are not connected by loose lengths of thread to show above the welt in the coinpleted shoe and become entangled with the line of inseam stitches, preventing the ready removal of the welt, if so desired. In the illustrated embodiment of the invention a thread cutting knife is pivotally supported upon the back .gage and is provided with a cutting edge 111 arranged to shear the thread against one edge of a rectangular slot 112 through which the thread passes` The thread cutter 110 is 4securedin an arm 115 of a bell crank lever pivotally supported upon the back gage at 116 and having its opposite arm 114 connected to the back ga e carrier through a tension spring 117. Te

movement 4of'the bell crank to carryxtlie into an inoperative position is liinifod knife by a stopllB formed upon the backvgage and bearingagainst the rear face of thearm 114. From an inspection of Figs. 4 and 5 of the drawings it will be observedthat the cooperating shearing faces of the knife and back gage are positioned at an angle to the plane o movement of the knife, thus the thrustutthe knife due to the shearing of theihrad-is inV a p ane approximately normaLt; the axis. an `jas there is neonsideru ng to force thekiiife in `a vertlcafl'direction away frompth back g a comparatively lghtknfe may y Y employed. Apmitive cutting stroke is im parted to the knife by the slide rod 120 which is supported in bearings formed Vin the machine frame and h a's its front end engaging"r with the arm 111 of the bell crank.

The slide rod 120 has the proper movements imparted to it by a cutter actuating lever 121 pivotallv supported upon the shaft ($9 and having one end connected to the slide rod and itsi opposite nd operatively connected:

through a cam roll 122 with a peripheral cam 123, shownin dotted `lines in Fig.

`The earn roll 122 is retained in engagement with rthe cani 123 by a springV 12-1 secured at one end to the shaft (39,` and positioned with its'opposite endbearingiagainst the rear faceof the lever 121.` With this colii structiong a rapid cutting stroke is positively imparted to-the knifel110, atthe completion dof which the slide rod 120isg moved out lof engagement witlrthe bell crank, 'which' is' then oscillatedby the spring '117 tomove the cutter into an inoperative position.

ln the present invention` the machine is automatically stopped at the completion of the predetermined c'vcle of operations and in the illustrated embodiment of the invention this is accomplished ina single revolution of the cam shaft.- The cam shaft is rotated by a drive pulley 135 loosely journaled upon the shaft and providedwith a conical clutch face arranged to engage at predetermined intervals with a. cooperating clutch face formed -u-pon. a spider 137 secured tol the-shaft Thetwo clutch faces are held in engagement withoneanother during one complete revolution lthe cam shaft by any suitable form ofonerrevolution clutch which is 'arranged to Positively stop therotation ofthe Ycam-shaft upon releasing the clutchrw'lfheclutch Y is controlled by. a` slidfngltrip-member 138 operativelyconnected with the treadle through a'treadle rod 140 and yslide 1:11. After the slide 138 has been depressed sulliciently to allow the'clutch to engage and start the machine it' is 'automatically disengaged lfrom the treadle and allowed to return to* its normal position independentlyof the position of the ti'eadle. To this end the slide 1141 Iis provided with a hook shapedy upper end 142 engaging with a coperatinghook 143 The "slide and trip member are disengaged by a stationary cam member 115 secu'l'ied to the machine frame and cooperating'with an inclined face formed upon the slide 1-11 to move the slide to the right, as shown in Fig. 3, and disengage thc two hooks. The member 138 and slide 141 are Viildependently returned to their normal positions by tension springs 14o and l-l7 tivelyY to the two.l

rl`hc mode of as follows'lhe lasted'shoe isiirst manipulated bv the operator to positioithe chan nel guide against thcinsidc `ol" the `lip of the insole at'a point where the` insertion ofthe tread fastener will n'otfinterfere with any olthe metallic fasteners in the shoe. rThe machine is Vthen stirte'dLcausing the back gage to be viclilingly advanced into an operative position in which it locked, clamping the shoe firmly during the formation. of the ,stitch and pressing the upper and `lip of the insole togcther'to cause the thread fastening to hold theln tightly, as shown clearly in lfig. 10.1, 'lheineedle is then advanced to pass the first loop of thread through thc upper and lipof the insole from the outside of th'c shoe, and the loop is engaged and held during the retracting morena-ntof the needle by the hook shaped end of the thread finger. The needle is then witlulrawn from the work and the needle carrying slide is actuatedrto impart connected respec operation of the machine is cate it in position for the next advancing movement. The needle is again advanced to" pass a second loop of thread through the work, this second advancing movement being greater than the first tofallow the thread finger to carry the first loop between the upper side of the second loop and the shank of the needle. After the thread finger has completed the passing of one loop through the other, the needle is retracted, binding the second loop upon the first and holding the first loop in positionduring the withdrawal of the thread finger. The needleAthen continues its retracting movement until completely withdrawn from the work and during this movement the take-up is actuated to pull the second loop into the work and lock the stitch.

From an inspection of the drawings, it will be noted that `the needle has a fixed throw to always pass each loop of thread through the work a predetermined distance with relation to the channel guide. During the feeding movements of the needle, the proper amount of thread is drawn from the `supply and as the inside of the lip upon which the loops, are formed is .always positioned in the same relation to the movement of the needle, the loops Will always be passed through the samedistance and the thread supply will automatically give up varying amounts of thread, depending upon the thickness of the work. n a like manner, as the take-up lever has a predetermined movement imparted thereto, the thread lock is alwaysdrawn into the work the same distance, re ardless of the thickness of the work an without necessitating any automatic measuring instrument or other device which is regulated for the thickness of the work. U on the completion of the fasten ing the tiiread cutter is actuated to shear the supply thread close to the surface of the upper and the back gage is then retracted to release the shoe, Upon the completion of the predetermined cycle of operations, the machine is automatically stopped and it will be observed from an inspection of the drawings that this complete cycle is performed in one revolution of the cam shaft, thus enabling the operation of the machine to be controlled with a simple and compact mechanism. In order to retain the toe portion of the upper in place, a fastener is inserted at one side of the toe and before the cutting mechanism is set into operation the treadle is depressed to render this mechanism inoperative. The cycle of operations` with this exception, is performed in the usual man ner and when the fastener is completed the shoe is turned to pass the supply thread about the toe, the tension device enabling the thread to be bound tightly against the upper. After the thread has been passed completely about the toe the shoe is again positioned-in the machine and a second fas tener inserted on the opposite side of the toe, the vtwo fasteners anchoring the toe thread tightly in place to retain the toe of the upper in its lasted position. It will be noted that this operation of' applying the toe thread is readily accomplished becausev of the fact that the supply thread `is drawn from the outside of the shoe and when a fastener is completed the supply thread is in convenient position either to be servednor utilized as a toe binder.

While it is preferred to employ the spef' cific construction and arrangement of parts shown and described, it will be understood that; this construction and arrangement is not essential except so far as specifiedinthe claims, and may be changed or modified without departing from the broader features of' the invention.
